confounded, and which has only four white lines instead of six, 

 on the thorax. The larva of the latter, moreover, differs from, 

 that of our lineata. Dr. Hornbeck has sent to me from St. 

 Thomas, W. I., specimens which vary a little, but are not speci- 

 fically distinct from the lineata of the United States. 



2. D. Chamcenerii. H. — Epilobii. H. (Catalogue.) 



Olive-brown ; fore-wings with a sinuous buff-colored stripe, 

 indented before, beginning near the base of the inner margin and 

 extending to the tip, and a dark olive-brown tapering stripe behind 

 it, a black spot at base, a white dash and a diamond-shaped black- 

 ish spot before the middle ; hind- wings dark brown, with a trans- 

 verse rose -colored band, including a white spot near the body and 

 a deep red one before the anal angle ; inner edge of the fore-wings 

 and fringe of the hind-wings whitish ; palpi white below ; a 

 white line above each eye extending on the sides of the thorax, 

 where it is bounded above by a black line ; abdomen with a dor- 

 sal series of white dots, two black and two alternating white 

 bands on each side of the base, and two narrow transverse white 

 lateral lines near the tip ; segments beneath edged with white. 

 Expands from two and three quarters to three inches. Larva 

 green, somewhat bronzed, dull red beneath ; with nine round 

 cream-colored spots, encircled with black, on each side, and a dull 

 red caudal horn. It lives on the Epilobium angvstifoliuni, and 

 (as Mr. Leonard informs me) transforms in the ground, without 

 making a cocoon. Inhabits New Hampshire. 



The larva very closely resembles that of D. Galii, as figured 

 by Roesel, III, Tab. VI, Fig. 1, 2. For a specimen of it, and 

 for the insects in the winged state, I am indebted to Mr. Leonard, 

 by whom they were raised. This species is the American rep- 

 resentative of D. Galii, and is also allied to several other Euro- 

 pean species, such as D. Epilobii, EsuIcb, Amelia, Tithymali, 

 Dahlii, Euphorbice, &c. ; but I am satisfied that it is perfectly dis- 

 tinct from all of them ; and the long description which I have 

 given of it will render it easy to discover in what respects it differs 

 from them. Moreover it is a legitimate species, which is more than 

 can be said of all of the above-named European insects, some of 

 which are now admitted to be hybrids. Mr. Kirby (Fauna Bo- 

 reali- Americana, IV, p. 302,) describes a North American species, 

 under the name of D. intermedia, which, according to him, has 

 the stripe on the fore-wings of a pale rose color, and wants the
